What is the purpose of encryption?
Answer:
Encryption enhances the security of a message or file by scrambling the content. To encrypt a message, you need the right key, and you need the right key to decrypt it as well.It is the most effective way to hide communication via encoded information where the sender and the recipient hold the key to decipher data.

) How much dry salt must be added in 150 kg of aqueous salt solution in order to
increase its concentration from 15% to 40%? (10 Marks.
To archive a concentration of 40%, you need to add 62.5 kg of salt.
How much salt must we add?
First, we have 150kg of aqueous salt solution with a concentration of the 15%, which means that the 15% of 150kg is salt, so we have:
0.15*150kg = 22.5 kg of salt.
Now we want to add a quantity M of salt, such that the new concentration of salt is of 40%.
The new mass of the mixture will be:
150kg + M
The new mass of salt will be:
22.5kg + M
The concentration of salt, in decimal form, will be:
(22.5kg + M)/(150kg + M)
The above quotient must be equal to 0.4 (40% in decimal form), then we solve:
(22.5kg + M)/(150kg + M) = 0.4
(22.5kg + M) = 0.4*(150kg + M)
(22.5kg + M) = 60kg + 0.4*M
M - 0.4*M = 60kg - 22.5kg
0.6*M = 37.5kg
M = (37.5 kg)/0.6 = 62.5kg
So you need to add 62.5kg of salt.

10.) A solid circular titanium control rod at 7,000 lb axial tension force where stress must not
exceed 42,000 psi. Assume that the modulus of elasticity of the titanium is 16,500,000 psi
and that the rod must elongate no more than 0.20 in. Determine (a) the minimum rod
diameter (precision 0.00) and (b) the maximum rod length (precision of 1).
The minimum rod diameter is 0.46 in and the maximum rod length is 78.6 in.
What is diameter?Diameter is defined as the distance that runs through the center of a circle from one point to another on its surface. It can also be thought of as the circle's longest chord. The diameter of a sphere can be defined using either of the two methods.
Given tension axial force = 7000 lb
Maximum axial tensile strength = 42000 psi
σ = P /A = P / λ / 4 x d²
The minimum rod diameter = 0.46
Elongation in rod = 0.2 in
= FL / AE
Maximum length of rod = 78.6 in
Thus, the minimum rod diameter is 0.46 in and the maximum rod length is 78.6 in.

Given: A=1, B=1, C=1 for a 3-input NOR gate, what is the output value?
Answer:
0
Explanation:
A NOR gate gives you the inverted output of an OR function. In numerical terms, the OR function gives you the maximum of the inputs:
A+B+C = max(A, B, C) = max(1, 1, 1) = 1
Then the output of the NOR function is its inverse:
(A+B+C)' = (1 -max(A, B, C)) = 1 -1 = 0
The output value is 0.

A turbine engine compressor which contains vanes on one side of the impeller is a
1. Single entry centrifugal flow compressor
2. Single entry axial flow compressor
3. Double entry axial flow compressor
4. Double entry centrifugal compressor
The turbine engine described above is a Single-entry Centrifugal Compressor.
What is a Single-entry Centrifugal Compressor?
Also known as a Single-Stage Centrifugal compressor, this type of engine combines one impeller with an inlet guide vane that is associated and a diffuser.
It is used for increasing the kinetic energy of the gas with a high-speed impeller. This energy is then converted into heightened pressure within the diffuser. The correct answer, thus, is A.
In order words, they are used for compressing large volumes of gas into small pressures.
